Dyn-X Input Modules

Based on state-of-the-art, new technology, and with a useful analysis capacity exceeding 160 dB in one range, Brüel & Kjær introduces a new, revolutionary set of input modules.

These will not only save you time and work, but will also allow you to make measurements not previously possible. Gone are the days of trial runs, overloads and under range situations. Gone are the days of repeating measurements, and setting input ranges. 

This new range of modules covers all signal levels from 0 to 10V in one range – and there are no technical drawbacks. In fact, with these new modules all you have to worry about is choosing the right transducer.

Dyn-X

• When time is limited 
• When you need to get the measurement right first time
• When signal levels are unknown 
• When it’s difficult to overview the whole measurement scenario 
• Where there’s minimal user interaction 
• When testing is unattended 
• For high-dynamic applications 

160 dB in One Range

To date, high-quality transducers and preamplifiers have outperformed measuring equipment with regard to linearity and dynamic performance, being able to deliver a noise- and distortionfree signal over a dynamic signal range of 120 to 130 dB broadband and 160 dB narrow-band. 

Now, with Dyn-X technology, the entire measurement and analysis chain, from the transducer to the analysis results, for the first time matches or outperforms the transducer used for measurement. This eliminates the need for an input attenuator for ranging the analysis system input to the output of the transducer. All that you need to do to get excellent results is choose the right transducer. 

Accuracy, Safety and Efficiency

With no input range to set, you no longer have to worry about overloads, underrange measurements or discussions about the validation and verification of measurement results. And with no need for trial runs to ensure that the input range is correct, you have a far greater certainty of getting measurements right first time. The measurement situations and applications below are examples of where the new Dyn-X technology can be usefully employed: 

When you need to get the measurement right first time	Crash testing Destructive testing Heavy machinery – run up/coast down
Where there’s minimal user interaction	Road testing Field testing
When time is limited	Test cells Wind tunnels Road testing Flight testing
When testing is unattended	Production line Noise monitoring
When signal levels are unknown	Run up/down Field testing
When an overview of the whole measurement scenario is difficult	When measuring many channels When combining more signal types: Vibration, Sound, Temperature, Pressure, RPM, etc. Test cells In-car testing Sound, vibration and other parameters involved
High-dynamic applications	Impulsive testing, room acoustics Run up/down Electroacoustics Structural measurements

160 dB analysis in one range. FFT measurement of a 1 KHz signal 80 dB below full-scale. Note that noise and all spurious components measure 160 dB below full scale input
